Unwinding Short-Range Entanglement. (arXiv:1804.11236v1 [quant-ph] CROSS LISTED)  hep-th updates on arXiv.org on 2018-5-05 1:16am GMT Authors: Abhishodh Prakash, Juven Wang, Tzu-Chieh Wei Symmetry-Protected Topological (SPT) phases are short-range entangled (SRE) gapped phases of quantum matter protected by global symmetries, that cannot be unitarily and adiabatically deformed to a trivial phase without closing the gap or breaking symmetry. In this work, we show that,… Read more →

Are there really conformal frames? Uniqueness of affine inflation. (arXiv:1802.01247v2 [gr-qc] UPDATED)  hep-th updates on arXiv.org on 2018-4-28 8:09am GMT Authors: Hemza Azri Here we concisely review the nonminimal coupling dynamics of a single scalar field in the context of purely affine gravity and extend the study to multifield dynamics. The coupling is performed via an affine connection and its associated… Read more →

H-theorem and Maxwell Demon in Quantum Physics. (arXiv:1804.06886v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-4-21 2:11am GMT Authors: N.S. Kirsanov, A.V. Lebedev, I.A. Sadovskyy, M.V. Suslov, V.M. Vinokur, G. Blatter, G.B. Lesovik The Second Law of Thermodynamics states that temporal evolution of an isolated system occurs with non-diminishing entropy. In quantum realm, this holds for energy-isolated systems the evolution of which is described by the so-called unital… Read more →

A Finite Theory of Qubit Physics. (arXiv:1804.01734v1 [quant-ph])  quant-ph updates on arXiv.org on 2018-4-07 1:45am GMT Authors: T.N.Palmer Hardy’s axiomatic approach to the quantum theory of discrete Hilbert Spaces reveals that just one principle distinguishes it from classical probability theory: there should be continuous (and hence infinitesimal) reversible transformations between any pair of pure states – the single word `continuous’ giving… Read more →

Decoherence and Determinism in a One-Dimensional Cloud-Chamber Model  Latest Results for Foundations of Physics on 2018-4-01 12:00am GMT Abstract The hypothesis (Sparenberg et al. in EPJ Web Conf 58:01016, [1]. http://dx.doi.org/10.1051/epjconf/20135801016) that the particular linear tracks appearing in the measurement of a spherically-emitting radioactive source in a cloud chamber are determined by the (random) positions of atoms or molecules inside the… Read more →

The Meaning of the Wave Function: In Search of the Ontology of Quantum Mechanics

Reviewed by Peter J. Lewis, Dartmouth College Shan Gao (2017), The Meaning of the Wave Function: In Search of the Ontology of Quantum Mechanics. Cambridge: Cambridge University Press. Shan Gao has written an exemplary book on the nature of the wave function—its theoretical role, the ontology it represents, and how understanding this ontology can contribute to solving the measurement problem….
